And i know of no Lomborg, and assure you that i've not read any such book. I'm not demanding a standard of proof, and i'm not demanding anything, in fact. I do recall that as recently as 25 years ago, many scientists were saying we were headed into a new ice age. The response was rather ho-hum. However, when a threat of global warming was posited, the government grants for long, expensive and well-paying research began to fall from heaven as manna. Pardon me for being sceptical of the motives of university researchers. Much of the data to support the contention of a trend toward global warming comes from records of weather agencies around the world, which, typically, operate in or near the "heat islands" of cities. Add to that the fact that such data has only been collected for about a century, and only collected on a world-wide reliable basis for considerably less time than that, and my scepticism only grows. In fact, i consider Sumacs report about shrubbery (with or without little white fences) to be a more significant bit of evidence than statistical data of a questionable provenance.
Quote:The more complex a system studied, the more we must deal with probables rather than certainties.
I heartily agree--and we know precious little about how the entire climate system works. Scientists have only recently begun to study the part which the oceans play in this very complex system. Basically, i think that there are three main points to consider: Who immediately benefits most and in what manner from attention being focused on this issue? The answer to that is the members of the scientific community (most of whom are academics obliged to justify their research in order to get local or governmental grants) upon whom we depend for answers to the questions raised. The next point is historical: What information do we have about climate in the past, and what does it suggest to us? For this, i think the issue of what does it suggest is open to a lively, and heated (all punning is intended) debate. It is worth noting, as i did above, that the world was once, and, in geological terms, quite recently, a much warmer place than it now is. If this is accepted as an accurate description of what history has to offer on the subject, one is inevitably lead to the final issue: Has this trend reached a crisis level. Your point about the size of the human population of the planet is the most significant to me. If it can be definitely shown that disaster looms, then almost any measure is justified to reduce greenhouse gases. Do me the courtesy of not lumping me with the "business community" on this one, i simply pointed out in my first post here that nothing is proven, i did not say there can't be a problem, nor have i lined up with any statement made by the Shrub (heeheeheeheeheehee, shrub--get it?) on the subject. Most of all, i remain sceptical of the motives of people on both sides of this issue--too many constituencies, too many agendae.
